A series of tremors and aftershocks has shaken up Shawville and Ladysmith, Que., northwest of Ottawa, following a 5.2-magnitude earthquake that shook the region in mid-May.

The tremors — ranging from the initial 5.2-magnitude earthquake to a 1.4-magnitude aftershock nine days later — are all centered close to Ladysmith, northeast of Shawville.

They've caused damage to St. John's Lutheran Church in Ladysmith.

Marlene Pasch is a member of the church council. The church has suffered large new cracks in the walls, with pieces of plaster scattered about. Window frames were also damaged.

"Aftershocks are a natural part of the earthquake process. The main shock happens, the big earthquake, and then the stresses are redistributed," said John Adams, a seismologist for Natural Resources Canada.
